A wealth of more detailed information about running Linux in Thinkpads is available at ThinkWiki.

Summary
Laptop Model
IBM T43 2669-WE5. This model is not listed in tabook because it's a special version for Penn students. It's basically a 2669-CEU with 1GB RAM and Bluetooth added.

Notes
ACPI
Adjusting the LCD brightness through software doesn't work. The buttons on the keyboard do work, though. acpid also doesn't pick up events from the power button for some odd reason.
SATA drive interface
Make sure you disable all ATA/ATAPI device support. Even though the drives themselves are PATA, they are connected through a SATA interface, and libata recognizes them as SATA drives.
HDAPS (Hard drive active protection system)
Follow the tutorial at ThinkWiki.
Hibernate (aka Suspend-to-Disk)
You must use vbetool with the hibernate script to suspend while running X.
Video
If you want to be able to hibernate the laptop while running X, you have to disable DRI in your xorg.conf. The laptop will suspend with DRI enabled, but completely locks up on resume.
Analog VGA Out
The button in text mode just switches between built-in and external displays, but won't cycle to where it displays to both. You can, however, use /proc/acpi/ibm/video to get around this.
Under X, the ATI driver will clone the display to the output. My external LCD at first refused to sync to the signal because the rate was too low. I set “IgnoreEDID” option to “on”— and put my LCD's HSync and VRefresh values in “HSync2” and “VRefresh2” and then it worked fine. I have not yet tried Xinerama and spanning the desktop across the internal and external monitors.
S-Video Out
S-Video works only if you're already plugged into the projector/TV when you power on the laptop.
Touchpad / Pointing Stick
You need two separate “InputDevice” entries in xorg.conf to get these to work together. /dev/input/mouse0 is the touchpad, which uses the synaptics driver, and /dev/input/mouse1 is the pointing stick, which can use the regular mouse driver. If you also want to be able to use a USB mouse, then add yet another “InputDevice” section using /dev/input/mouse2. The USB mouse must be plugged in when you start X for it to work.
Modem
The “MC97 Modem” driver in the kernel's ALSA subsystem detects the modem, and running slmodemd -c=USA -d=1 -g=dialout -a modem:1 will allow me to send commands to the modem using minicom, but the modem doesn't detect a dial tone and won't dial any numbers. I never use the modem anyway, so I don't feel like it's worth my time to get it working.
Audio
The volume up/down and mute buttons on the keyboard appear to control a hardware mixer entirely independent of the sound card (and thus ALSA). If you're not getting any sound and the ALSA mixer isn't set to mute, then try hitting one of the volume buttons.
